Collapse & Return to Top
The main function of the cooling unit is to remove waste heat and return treated air to the room at the required temperature. The control strategies employed by the cooling unit depend upon the deployment strategy of the cooling group. In an In-Row environment, the cooling unit supplies constant-temperature supply air to the common cold aisle. The fan speed is modulated to ensure that the required volume of air reaches the IT equipment. The fan speed is determined by the difference between the cooling setpoint and the maximum rack air inlet temperature of the cooling group.
